How often do most people change these? Is there a way to know if you need to?

you know when to change it -- you will suddenly stop hearing, even with a good battery. frequency varies by the person. for me, it is almost the same frequency as the need for battery replacement -- once per week.

In my case, it depends on how much ear wax accumulates in the filter. Sometimes i will try to dislodge a piece of earwax if it only blocks the opening partway and I can get a brush bristle on it to knock it out. IF more than 50% of the opening is blocked, I change the filter. IT really depends on how waxy your ears are. Note that if you think your aid is not working, change the filter and see if it helps,before you take it to your doctor. Don't ask my why I recomend this.

When mine gets clogged even if I put in a new battery I still can't hear. Then I know I need to change the Wax stop. Mine usually last a couple of weeks.

The only way I know is when the hearing aid stops working and replacing the battery doesn't do the trick. If this happens it's the wax trap that needs replacing. I always change both at the same time

I have to change my husband's about once a week due to wax build up. The hearing aids do not work if the wax guards need changing.

They are indeed easy to change; and you'll be doing that a lot. I bought two sets and returned them both. The effect is beautiful, however the batteries drain even when the unit is off. I used mine approximately 4 times for less than a minute each time, at night just to view the effect. This was done over a course of about a month; then the batteries died.

depends how often it runs, but in my case with very heavy constant use I'm changing 2-3 times per year. Basically fall, winter and spring (not used in summer).

I tend to change mine about 2-3 times a year and I don't use the extra functions all the time

to be honest I am not sure we have had for a little over a year and I have never had to change them...prob played with 4x a month

The best practice is to change it every 8 to 12 months. Even flowing strongly after that time filter could have lost part of its filtering properties.

Sorry, I don't know. I never changed one, as they last 10 or 20000 hours. If yours failed, take it back where you bought it and get a replacement. (Incidentally, the in-house product at Home Depto, is much better)

I change them annually with my smoke detectors and such. Have not had to do it more.

In the Instructions it says when to change, I think once a year under normal use.

It all depends on how much you use them, but for me i use them everyday with high dust content so I replace them every few months

I just replace according to the schedule they provide which for me is about once a month. I forget how to figure it out exactly. I have also read about how to refresh them but never done it myself.

You can change it as many times as you want. Just don't lose the little metal insert that comes with it. That is what you use to change to combination.

Yes. I change about once a year, but be careful to check out if the Timer works. My last purchase of 8 units resulted in one not working. I didn't send it back because it just wasn't worth the trouble...and this is not the first time that I had the same problem. Talking everything into consideration...I really like these timers. FAR BETTER than several others I have purchased.

I change mine every year or every other year. Just check it and see what it looks like. If it looks like it is dirty enough to impede the air flow then change. Thats a bonus to how easy these just slide in and out.

As far as I know, they are pretty much disposable. I haven't needed to change it. However I don't think you can.

Depends on conditions how well the safe seals and how often your in it, my guess would be 2 every six months. I use two in my toolboxes and change them every six months to a year depending on environmental conditions.

You can if you want to just make sure to change it at least once everyday thats what I do so far it seems to be working:)
